    Ivanhoe’s 2026 Kakula copper dip and 2027 ramp-up: planning notes for mine engineers

    Ivanhoe’s 2026 Kakula copper dip and 2027 ramp-up: planning notes for mine engineers

    First reported on MINING.com

    30 Second Briefing

    Ivanhoe Mines expects contained copper output at the Kamoa-Kakula complex in the DRC to fall to 380,000–420,000 tonnes in 2026, down from 437,061 tonnes of copper concentrate in 2024, before rising about 30% to 500,000–540,000 tonnes in 2027 at grades of 3.5–4.5%. Seismic-induced flooding in May halted underground mining for about three weeks, with dewatering now 70% complete in the western zone and 60% in the eastern zone, and 13.4 km of workings rehabilitated, including 4.6 km dewatered. A revised life-of-mine plan due late Q1 will assess lifting mining rates to 17 Mt/y, up from about 6 Mt of ore expected in 2026, and a potential new concentrator.

    Technical Brief

    • Dewatering completion is asymmetric: 70% in the western zone versus only 60% in the eastern zone.
    • Rehabilitation has covered 13.4 km of underground workings, including 4.6 km already dewatered and re‑entered.
    • Analysts flag that investors are tracking dewatering percentages more closely than tonnage guidance, effectively treating water control as a leading safety indicator.
    • For other deep, high‑grade underground operations, the case underlines the need for robust seismic monitoring and rapid‑deployment dewatering capacity in life‑of‑mine planning.

    Our Take

    With Kakula copper grades guided at roughly 3.5–4.5% and a potential mining rate under review of up to 17 Mt/y, the Kamoa-Kakula complex in Congo remains positioned as a very low-cost, high-grade supplier in a copper market where other majors like BHP are pursuing growth mainly through large-scale M&A, as seen in its recent approach for Anglo American.

    The three-week shutdown and ongoing dewatering/rehabilitation at Kakula (13.4 km rehabilitated, 4.6 km dewatered so far) underline how seismic and hydrogeological risk is becoming a recurring operational theme in our safety-tagged copper coverage, which can tighten near-term supply even at otherwise well-capitalised assets.

    Given that the Democratic Republic of Congo accounts for about 70% of global cobalt mine production in the referenced data, any sustained disruption or mine-plan change at Kamoa-Kakula could have knock-on implications for cobalt by-product availability alongside copper, particularly for battery supply chains tracked in our critical-minerals pieces.

    EnergyX enters nuclear materials market: isotopes, Smackover project lens for mine planners

    Energy Exploration Technologies (EnergyX) has launched its NUKE-it platform to produce nuclear-grade lithium isotopes, targeting 15% enriched Lithium-6 for tokamak fusion and 99.999% pure Lithium-7 for thorium molten salt fission reactors. Building on its GET-Lit DLE extraction and refining suite, the company is tying isotope production to its Lonestar Lithium project in the Smackover formation, where it now controls 47,500 acres of lithium-rich brine after a US$26 million land deal. Uranium and thorium materials from upper Smackover limestone reservoirs in Arkansas and Louisiana are planned as follow-on products.

    America can’t defend itself with Chinese minerals: offshore supply lens for mine planners

    America’s near-total reliance on China for critical minerals – including 90% of global rare earth magnets, all ultrapure dysprosium and samarium for defence uses – is framed by NOIA president Erik Milito as a direct national security risk. Milito backs President Trump’s “Unleashing America’s Offshore Critical Minerals and Resources” executive order to fast-track offshore exploration, arguing that polymetallic nodules and shallow-water deposits could supply nickel, cobalt, manganese and copper at multi-generational scale. He points to decades of US sediment dredging and modern offshore robotics, monitoring and containment as evidence that well-regulated seabed mining can be run with controlled environmental impacts.

    Hancock–Maaden Saudi JV: exploration and project delivery lens for mine planners

    Hancock Prospecting and Saudi state miner Maaden have formed a joint venture to run exploration, development, mining, sales and marketing across licensed areas in Saudi Arabia, including five new exploration licences in the Nabita Ad-Duwayhi Gold-Belt. The partnership, announced alongside Round 9 licence awards at the Future Minerals Forum in Riyadh on 14 January, aims to accelerate discovery and project delivery under the Kingdom’s Vision 2030 pro-mining framework. Hancock brings large-project experience from Australia’s A$10 billion Roy iron ore project, while Maaden targets rapid build-out of a regional mineral hub and local talent pipeline.
